PPa-GPLGLAG-PEG

Pyropheophorbide-a-GPLGLAG-PEG/mPEG-GPLGLAG-Pyropheophorbide-a is an MMP-2 enzyme responsive photodynamic amphiphilic PEG derivative, which is a popular intelligent delivery material in the field of precision diagnosis and treatment of tumors. PEG long chains provide spatial hindrance in the blood circulation, reducing protein adsorption and clearance by the reticuloendothelial system, ensuring long-term circulation stability of the system; After reaching the tumor site with high expression of MMP-2, the GPLGLAG peptide segment is specifically cleaved, and the PEG hydrophilic layer is rapidly peeled off, exposing the internal PPa photosensitive group.
